Effect of Annuloplasty for Mitral Valve Prolapse
Mitral valve prolapse (MVP) is the most common cause of primary mitral regurgitation (MR), which represents leaflet or chordae elongation and is frequently accompanied by ruptured chordae. In almost all patients with this entity, annular dilatation is a common lesion. It is well known that the normal annulus has a unique saddle shape, but the saddle is flattened in MVP, and its dynamic characte...
متن کاملMitral annuloplasty vs valve replacement for mitral insufficiency.
evidence of reduced venous return and alternating end-diastolic fiber length as causative factors. To the Editor: Attie et al.' reported their experience with valve replacement in children with mitral insufficiency. They divided their patients in three groups, depending on the type of prosthesis: mechanical valves, porcine xenografts and dura mater valves. Follow up times were 6.3, 3.3 and 1.9 ...
متن کاملMitral valve area during exercise after restrictive mitral valve annuloplasty: importance of diastolic anterior leaflet tethering.
BACKGROUND Restrictive mitral valve annuloplasty (RMA) for secondary mitral regurgitation might cause functional mitral stenosis, yet its clinical impact and underlying pathophysiological mechanisms remain debated. OBJECTIVES The purpose of our study was to assess the hemodynamic and clinical impact of effective orifice area (EOA) after RMA and its relationship with diastolic anterior leaflet...
متن کاملTransvenous mitral valve replacement after failure of surgical ring annuloplasty.
To the Editor: Mitral valve repair is the preferred treatment for itral regurgitation (MR). However, failure or recurrence of MR ight occur. Re-operation might carry a high risk in patients with omorbidities. A few reports have suggested the feasibility of ranscatheter mitral valve replacement after failure of surgical ring nnuloplasty (1–4). We report here the first series of transvenous itral...
متن کاملDehiscence of mitral valve annuloplasty: a three-dimensional diagnosis.
A 74-year old patient underwent aortic valve replacement and mitral annuloplasty (Edwards Lifesciences Physioring, 34 mm). Five weeks post-surgery, he was readmitted because of heart failure due to a severe residual mitral regurgitation. Three-dimensional (3D) echocardiography clearly demonstrated the posterolateral area of dehiscence. He underwent successful surgical refixation (Fig. 1 and Sup...
